The first trimester is the most vulnerable and sensitive period of the entire pregnancy. In this part of the pregnancy miscarriages account for almost four fifth of all pregnancy losses.

The first trimester miscarriage may be in form of a chemical pregnancy, blighted ovum and a missed miscarriage. A chemical pregnancy refers to a very early miscarriage. In this case the positive pregnancy test was achieved before the woman's period is supposed to occur and the miscarriage typically occurs before a heart beat is visualized on an ultrasound. A blighted ovum is a type of miscarriage in which a fertilized egg attaches to the uterine wall but there are no signs of the embryo. The embryo simply does not develop. And finally, a missed miscarriage includes the loss of a baby after it has grown to a certain size.

Causes of First Trimester Miscarriages

In majority of cases first trimester miscarriages are associated with chromosomal abnormalities. Improper number of chromosomes or their structural abnormalities are recognized as irregular and the body rejects the embryo. Furthermore, miscarriage in this period of pregnancy may be induced by hormonal imbalances or certain health conditions (already existing diseases or illnesses acquired during pregnancy).

There is also a connection between a woman's lifestyle and early miscarriage. Improper diet and intake of certain medications, drugs and alcohol may be a trigger for early miscarriage. Even smoking may cause the loss of a baby. Miscarriage in the first trimester can be a consequence of accidents such as falls and in general it affects older women more comparing to young mothers.

Symptoms of First Trimester Miscarriages

An initial symptom of early miscarriage is back pain which may vary in intensity. Furthermore, a woman may also experience a sudden weight loss. One more characteristic of early miscarriage is a mucus discharge which is usually white to pink in color. There is also a chance of blood clots and tissues coming from the vagina. And finally, bleeding is one more symptom of early miscarriage and it may or may not be accompanied by cramps.

Treatment for First Trimester Miscarriages

Once the miscarriage starts the body removes all the fetal tissue and there is no need for additional medications. In case that all the tissues have not been expelled a woman undergoes dilatation and curettage. Women who have had more than one miscarriage in the first trimester may require psychological consultation with their doctors in order to deal with the specific issue.

There is simply no cure for first trimester miscarriage since the majority of them are actually caused by chromosomal abnormalities.
